How to use
To operate the Weldline AI-12, first ensure the fiber ends are properly stripped, cleaned, and cleaved according to standard fiber optic preparation procedures. Place the prepared fibers into the designated holders within the fusion chamber, ensuring they are aligned correctly. Initiate the splicing process through the control interface, allowing the device to perform the automated alignment and fusion cycle. Once the splice is complete, inspect the connection for quality and apply a protective heat-shrink sleeve to the splice point using the integrated heating element.
What to consider before purchase
